of the blade, the guide or holder permitting an adjustmentof the tool tovarious angles.l In the accompanying drawings Figure v1 is a sideelevation, partly'in section, ofthe device. Fig. Zis a top plan. `Figs.3 and 41 i are perspectives of scraper'bladeswhich-Inay be sharpened byuse of theV device.

The holder for `the blade or workv has a base plate 6' which may beattached to the edge of a bench 'Y'V bygan. ordinary screwv clampB, thearm 9 of which is fixed tok ,the` under side of the plate 6 and isoiisetl at its 1 lower end to project under the bench. The" blade 10, tobe sharpened, clamped to (the. base'plate 6 by meansofa top plate 11and4 screws 12, the dimensions of the partsbeing such that blades ofvarious widths or thick? Vnesses may be held, in such manner that theedge of the .blade to be sharpened will Y project somewhat in front ofthe plate 6..,
